Thanks everyone for support and tips. This sister of mine is a bit blunt and says things without thinking and she upsets a lot of people because of this. The last time I went to the memorial which was about four years ago, she asked me why I was there! Not "how lovely to see you here" I just said because my husband wanted me to. I havn't been back since.
Sometimes I think it would have been easier to go now and then but I couldn't take the pressure to go on ministry.
Good luck to anyone else who is fading.
